Review for Unit 9

1.  Fizz Quiz.  See Blk 3 class scribblings here: Fizz Quiz – Unit 9 Chem11

2.  Review/Study/Ask questions!

Unit 9 Test format:   20 mc question and 3 calculation questions for the written section

Major topics:   vocabulary, conductivity of solutions, polarity of molecules and intermolecular forces and how it applies to solutions,  like dissolves like,  writing dissociation equations, calculating the concentration of ions in a solution

Pop Cell Lab Day 2

1.  Check the posted list of assignments to make sure you are up to date and that the marks have been entered correctly.

2.  Presentations

3.  Pop Cell Lab Day 2

4.  Retests for the written sections of ch19 and ch20 will be on Wed. May 27 and Wed. June 3 after school.  Here are some practice questions you should do and mark before you do the retest.  You can always do more questions of your own choosing!  Ch19 and Ch20 Retest Review Questions

Reminder:  Project #1 should be completed by next week.  Project #2 completed by first week of June.  Project #3 by 2nd week of June.

Redox Titrations

1.  Review of Balancing Redox Reactions:  2010 Balancing Question

2.  I will be able to calculate the molarity of a solution in a redox titration.  Redox Titrations (sec.7)

Read sec.7 and do # 28 and 32 (or as many as you’d like until you are confident you can solve them)

Test next class on Sections 1-7.  It will have a mc section and a written section.  There will be about 30 mc Q’s and 4 written Q’s.  You will need to bring a pencil and calculator.

The written section will consist of:  balancing redox reactions and redox titration calculations.

The mc section will consist of:  identify what is oxidized, reduced, the oxidizing agent and reducing agent, finding oxidation numbers, using the Standard Reduction Table in your data booklet to determine whether a reaction will occur or not, balancing using the half reaction method, balancing using the oxidation number method.

Pop Cell Challenge Day 1

1.  Project Presentations

2.  Pop Cell Challenge:  Brainstorm ideas of how you want to design the pop cell to generate the most voltage possible.  Test it out.  Modify your ideas.  Test it out again.  Keep a record of your ideas, observations, and results.

Here is the outline of the challenge:  Pop Can Challenge

Retests for ch19 and ch20 written sections will be held on Wed. May 27 and Wed. June 3 after school.  See me asap for review questions to help prepare for this.

Dissociation Equations and Concentration of Ions

1.  A Quick Review 2

2.

I will be able to write dissociation and ionization equations.

I will be able to calculate the concentration of ions formed in the solution.

See Blk 6 class scribblings here:  Writing Dissociation_Ionization Equations and Concentration of Ions  or Blk 3 class scribbling here:  A Quick Review 2

Sec. IX.5 – Nature of Solutions of Ions

Key vocabulary:  dissociation reaction vs. ionization reaction

Q: #28

Sec. IX.6 – Calc. the Concentrations of Ions in Solution

Based on the dissociation/ionization reaction, use the mole ratio to find the molarity of the ions formed.

Q: # 30, 32, 37

Next class:  Review and ask Questions!!  Unit 9 Qu-est the class after that.

 

 

Intro to Solution Chemistry

1.  Did you hand in your Ch8 Notes and Ch8 marked and corrected Workbook questions?

2.

I will be able to define key vocabulary terms involving aqueous solutions (sec. 9.1)

I will be able to identify characteristics of solutions that can conduct electricity and those that cannot conduct electricity.

I will be able to explain the saying “Like Dissolves Like”.

See guiding questions and practice questions from the workbook here:  Solution Chemistry

Interesting video on saturated solutions called “Fun with Sodium Acetate”

If the marks are updated, check to verify all is correct so far.  If you want to do an I Retest for Unit 8, see me asap to do your corrections and for practice questions to work on.

There is still a Unit 9 “Qu-est” and Unit 10 “Qu-est” and a Final Exam (20% of year mark) coming up so there are still lots of opportunities to show what you have learned!
